Abstract
Carica papaya (papaya) leaves has significant nutraceutical properties. However, it is speculated that papaya leaf curl virus (PaLCuV) and papaya ring spot virus (PRSV) can severely affect the therapeutic properties and alter the overall nutraceutical potential of papaya leaves. Therefore, we evaluated the bioactivity of the virus infected papaya leaves extract (PLE) compared to healthy PLE in C. elegans. Viruses infection were confirmed by visual inspection and PCR based detection. Anatomical changes and elemental analysis were analyzed through SEM-EDS. PLE were tested for life span extension and ROS scavenging activity on C. elegans. Infected leaves displayed typical symptoms of curling, distortion and anatomical analysis revealed closed and less number of stomata. Healthy PLE extended (24%) the life span of C. elegans with no significant change in ROS generation while in PaLCuV and PRSV infected PLE, were observed to have significant reduction in the mean life span of 15.4% and 17% with 1.2-fold and 1.9-fold increase in ROS generation.
